- Each non-leaking tear path includes a weakened path of the drape member that may be torn by hand.
- the adjustable cover also may include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path.
- an adjustable covering for use with a reduced-pressure treatment system includes a drape member having a first initiation edge and a second initiation edge and having a first side and a second, patient-facing side.
- the adjustable covering further includes a plurality of non-leaking tear paths formed on the drape member. Each non-leaking tear path includes a weakened path of the drape member that may be torn.
- the adjustable covering further includes a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path.
- a method of treating a tissue site on a patient with reduced pressure includes placing a manifold proximate to the tissue site, sizing an adjustable covering to fit over the manifold and a portion of the patient's epidermis to form a fluid seal, and fluidly coupling a reduced-pressure source to the adjustable covering to provide reduced pressure to the manifold.
- the adjustable covering includes a drape member having a first initiation edge and a second initiation edge and having a first side and a second, patient-facing side.
- the adjustable covering further includes a plurality of non-leaking tear paths formed on the drape member. Each non-leaking tear path includes a weakened path of the drape member that may be torn by hand.
- the adjustable covering also may include a first plurality of tear starters formed on a first initiation edge of the drape member. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path.
- the step of sizing the adjustable drape includes tearing the drape member along at least one of the plurality of tear paths to present a smaller adjustable covering.
- a method of manufacturing an adjustable covering for use with a reduced-pressure treatment system includes forming a drape member having a first initiation edge and a second initiation edge and having a first side and a second, patient-facing side. The method also includes forming a plurality of non-leaking tear paths on the drape member. Each non-leaking tear path includes a weakened path of the drape member that may be torn. The method further includes forming a first plurality of tear starters on a first initiation edge of the drape material. Each tear starter of the first plurality of tear starters is aligned with one of the plurality of tear paths. Each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along a tear path.

- FIG. 7 is the cross section of FIG. 6 after the tear path has been torn and a support layer and a backing layer have been removed.
- a reduced-pressure treatment system 100 for treating a tissue site 102 includes an adjustable covering 106 .
- the tissue site 102 may be, for example, a wound 104 .
- the wound 104 may include, without limitation, any irregularity with a tissue, such as an open wound, surgical incision, or diseased tissue.
- the wound 104 is shown extending through the epidermis 107 , or generally skin, and the dermis 108 and reaching into a hypodermis, or subcutaneous tissue 110 ,
- the reduced-pressure treatment system 100 may be used to treat a tissue, such as a wound of any depth, as well as many different types of tissue sites including open wounds or intact tissue.
- the tissue site 102 may be the bodily tissue of any human, animal, or other organism, including bone tissue, adipose tissue, muscle tissue, dermal tissue, vascular tissue, connective tissue, cartilage, tendons, ligaments, or any other tissue.
- the reduced-pressure treatment system 100 may include a manifold 112 , the adjustable covering 106 , and a reduced-pressure subsystem 114 .
- the manifold 112 is operable to distribute reduced pressure.
- the adjustable covering 106 provides a fluid seal over the tissue site 102 .
- Fluid seal or “seal,” means a seal adequate to maintain reduced pressure at a desired site given the particular reduced-pressure source or subsystem involved.
- the adjustable covering 106 may be sized by the healthcare provider at the time of application by hand without requiring cutting tools.
- the reduced-pressure treatment system 100 may include an attachment device 116 to help form a fluid seal between the adjustable covering 106 and the patient's epidermis 107 .
- the adjustable covering 106 has a first side 118 and a second, patient-facing side 120 .
- the manifold 112 is positioned between the second, patient-facing (inward-facing) side 120 of the adjustable covering 106 and the tissue site 102 .
- manifold generally refers to a substance or structure that is provided to assist in applying reduced pressure to, delivering fluids to, or removing fluids from a tissue site, e.g., tissue site 102 .
- the manifold 112 typically includes a plurality of flow channels or pathways to distribute fluids provided to and remove fluids from around the manifold 112 .
- the plurality of flow channels or pathways may be interconnected.
- the manifold 112 may be a biocompatible material that is capable of being placed in contact with a tissue site, e.g., tissue site 102 , and distributing reduced pressure to the tissue site 102 .
- manifold members may include, without limitation, devices that have structural elements arranged to form flow channels, such as, for example, cellular foam, open-cell foam, porous tissue collections, and foams that include, or cure to include, flow channels.
- the manifold 112 may be porous and may be made from foam, gauze, felted mat, or other material.
- the manifold 112 may be formed directly from a porous material, e.g., a foam, or from a material that is made porous, e.g., a solid member in which apertures have been applied.
- the porous foam may be a polyurethane, open-cell, reticulated foam, such as a GranuFoam® material manufactured by Kinetic Concepts, Incorporated of San Antonio, Tex., or Granufoam Silver® material manufactured by Kinetic Concepts, Incorporated of San Antonio, Tex.
- a polyvinyl alcohol foam such as White Foam, which also available from Kinetic Concepts, Incorporated of San Antonio, Tex., might be used in some situations.
- the adjustable covering 106 may be sized so that the adjustable covering 106 overlaps the wound 104 in such a manner that a portion of the adjustable covering 106 extends beyond the periphery of the wound 104 to form an extension 122 .
- the adjustable covering 106 may be formed from any material that provides a fluid seal.
- the adjustable covering 106 may, for example, be an impermeable or semi-permeable, elastomeric material. “Elastomeric” means having the properties of an elastomer. Elastomeric material generally refers to a polymeric material that has rubber-like properties. More specifically, most elastomers have ultimate elongations greater than 100% and a significant amount of resilience.
- the resilience of a material refers to the material's ability to recover from an elastic deformation.
- elastomers may include, but are not limited to, natural rubbers, polyisoprene, styrene butadiene rubber, chloroprene rubber, polybutadiene, nitrile rubber, butyl rubber, ethylene propylene rubber, ethylene propylene diene monomer, chlorosulfonated polyethylene, polysulfide rubber, polyurethane (PU), EVA film, co-polyester, and silicones.
- sealing member materials include a silicone drape, a 3M Tegaderm® drape, or a polyurethane (PU) drape such as one available from Avery Dennison Corporation of Pasadena, Calif.
- the adjustable covering 106 in some of the present embodiments may be selected to be less elastomeric in nature.
- the material allows for at least some plastic deformation or permanent stretching in response to a local stretching tool (e.g., local stretching tool 166 in FIG. 5 ) while maintaining the ability to stretch at least some.
- the attachment device 116 may be used to attach the adjustable covering 106 to the patient's epidermis 107 or another layer, such as a gasket or additional sealing member.
- the attachment device 116 may take numerous forms.
- the attachment device 116 may be a medically-acceptable, pressure-sensitive adhesive that is applied to the extension 122 of the adjustable covering 106 .
- the pressure-sensitive adhesive may span the entire width of the adjustable covering 106 .
- Alternative attachment devices may include, but are not limited to, heat-activated adhesives, sealing tapes, double-sided sealing tapes, pastes, hydrocolloids, hydrogels, hooks, sutures, or other device.
- the reduced-pressure subsystem 114 includes a reduced-pressure source 124 , which can take many different forms.
- the reduced-pressure source 124 provides reduced pressure.
- the reduced-pressure source 124 may be any device for supplying a reduced pressure, such as a vacuum pump, wall suction, or other source. While the amount and nature of reduced pressure applied to tissue site 102 will typically vary according to the application, the reduced pressure will typically be between ⁇ 5 mm Hg and ⁇ 500 mm Hg and more typically between ⁇ 100 mm Hg and ⁇ 300 mm Hg.
- the pressure may be ⁇ 90, ⁇ 100, ⁇ 110, ⁇ 120, ⁇ 130, ⁇ 140, ⁇ 150, ⁇ 160, ⁇ 170, ⁇ 180, ⁇ 190, ⁇ 200 mm Hg or another pressure.
- reduced pressure generally refers to a pressure less than the ambient pressure at a tissue site that is being subjected to treatment. In most cases, this reduced pressure will be less than the atmospheric pressure at which the patient is located. Alternatively, the reduced pressure may be less than a hydrostatic pressure at the tissue site.
- the reduced pressure delivered may be constant, varied (patterned or random) and may be delivered continuously or intermittently. Unless otherwise indicated, values of pressure stated herein are gauge pressures. Although the terms “vacuum” and “negative pressure” may be used to describe the pressure applied to the tissue site, the actual pressure applied to the tissue site may be more than the pressure normally associated with a complete vacuum. Consistent with the use herein, an increase in reduced pressure or vacuum pressure typically refers to a relative reduction in absolute pressure.
- the reduced pressure developed by the reduced-pressure source 124 is delivered through the reduced-pressure conduit 126 , through canister 128 , to a reduced-pressure interface 130 .
- the reduced-pressure interface 130 is a TRAC® technology port available from Kinetic Concepts, Inc. of San Antonio, Tex.
- the reduced-pressure interface 130 allows the reduced pressure to be realized within a sealed space below the adjustable covering 106 and realized within the manifold 112 .
- the manifold 112 may be placed proximate the tissue site 102 , e.g., wound 104 .
- the adjustable covering 106 may be adjusted to the desired size and placed over the manifold 112 such that the extension 122 extends beyond the periphery of the wound 104 .
- the extension 122 may be secured to the patient's epidermis 107 by the attachment device 116 in order to form a fluid seal over a portion of the patient's epidermis 107 and the manifold 112 .
- the reduced-pressure interface 130 may then be applied, if not already installed.
- the reduced-pressure conduit 126 is fluidly coupled to the reduced-pressure interface 130 and fluidly coupled to the reduced-pressure source 124 .
- the reduced-pressure subsystem 114 may be activated. Under reduced pressure, fluids will be delivered from the tissue site 102 to the manifold 112 and through the reduced-pressure conduit 126 to the canister 128 .
- the manifold 112 may have pre-cuts that allow the healthcare provider to size the manifold 112 to approximately the same size as the wound 104 or to a size desired for treatment.
- the adjustable covering 106 has non-leaking tear paths that facilitate sizing without requiring cutting tools.
- the adjustable covering 106 includes a drape member 134 having a first initiation edge 136 and a second initiation edge 138 ,
- the adjustable covering 106 may have a releaseable support layer 135 and a releaseable backing layer 137 .
- the releasable backing layer 137 may initially cover the attachment device 116 ( FIG. 1 ; not explicitly shown in FIGS. 2-4 ) and is releasably coupled to the second, patient-facing side 120 of adjustable covering 106 .
- the support layer 135 may be releasably coupled to the first side 118 of the adjustable covering 106 and may provide extra support to the adjustable covering 106 while the adjustable covering 106 is being deployed or prepared for deployment.
- the drape member 134 may be formed with a grain or a drape grain 139 . Analogous to cutting with or across a grain on a piece of wood, the drape member 134 is inherently easier to tear in the direction of the drape grain 139 and more difficult to tear cross-grain.
- the drape grain 139 is shown in a first direction that is parallel to a plurality of non-leaking tear paths 140 .
- the support layer 135 and the releaseable backing layer 137 may each have a grain, i.e., the support grain and backing grain, respectively.
- the drape grain 139 , support grain, and backing grain may all be aligned in the same direction.
- the adjustable covering 106 is formed with the plurality of non-leaking tear paths 140 formed on the drape member 134 .
- the plurality of non-leaking tear paths 140 may be linear as shown, circular, patterned, or any other shape.
- the plurality of non-leaking tear paths 140 includes a first non-leaking tear path 142 , second non-leaking tear path 144 , third non-leaking tear path 146 , fourth non-leaking tear path 148 , etc.
- Each tear path of the plurality of non-leaking tear paths 140 on the first initiation edge 136 may be aligned with a tear starter of a first plurality of tear starters 150 , e.g., a first tear starter 152 , second tear starter 154 , third tear starter 156 , fourth tear starter 158 , etc.
- the first plurality of tear starters 150 may be formed by forming a plurality of notches, cuts, or thinned portions on the first initiation edge 136 of the drape member 134 .
- the tear starters 150 may also be formed by adding a backing or platform that extends beyond a peripheral edge 141 of the drape member 134 and that has perforations that allow a healthcare provider to initiate a tear in the backing or platform before reaching an associated tear path 140 .
- Each tear starter of the first plurality of tear starters 150 is aligned with one of the non-leaking tear paths 140 .
- Each of the first plurality of tear starters 150 is adapted to facilitate the initiation of a tear along a tear path of the plurality of non-leaking tear paths 140 .
- a second plurality of tear starters 159 may be formed on the second initiation edge 138 .
- a plurality of weakened paths 160 correspond to the plurality of non-leaking tear paths 140 to facilitate tearing.
- the plurality of weakened paths 160 may be formed in a number of ways.
- the weakened paths 160 may be formed by local stretching, partial removal of drape material, or application of external energy.
- the drape member 134 may be locally stretched by forming a micro-ridge 162 that stretches the drape member 134 to form a portion with a smaller thickness t 1 than a thickness t 2 of the un-stretched portion 164 of the drape member 134 , i.e., t 1 ⁇ t 2 .
- FIG. 5 shows a local stretching tool 166 , which has a rotating wheel 168 with blunt pegs 170 , that forms the micro-ridges 162 resulting in a stretched portion with less material (i.e., t 1 ⁇ t 2 ) and thereby creating a weakened path.
- the blunt pegs 170 may be any impinging member that causes stretching but does not puncture the drape member 134 .
- a support surface 172 either hard or soft (e.g., foam), may be placed under the drape member 134 at the time the local stretching tool 166 is pressed against the drape member 134 . This process may be done using an automated manufacturing process.
- a non-limiting example of the second approach to forming the plurality of weakened paths 160 includes chemical etching with optical masks that remove material to create lines of weakness. Material may also be removed using heat or ultrasonic ablation.
- Other techniques may be used to weaken the drape member 134 to create the plurality of weakened paths 160 .
- external energy e.g., laser (heat) energy may be used to locally disrupt the semicryslalline nature of the polymer forming the drape member 134 to impart a localized physical weakness.
- the localized physical weakness forms the plurality of weakened paths 160 that form the plurality of non-leaking tear paths 140 .
- Lasers may also be used to advance crosslinking or degradation (for example by the activation of materials such as dyes in the polymer) to initiate controlled lines of physical weakness in the drape member 134 . All of the above would need to either reduce locally the material thickness to create a weakness, or in some other way cause a polymeric weakness which may be exploited during the tear along the grain of the material of the drape member 134 .
- portions of the drape member 134 between the locations of the plurality of weakened paths 160 may be fortified such that the plurality of weakened paths 160 are weak by comparison to the other portions.
- a plurality of a fibers may be added to the drape or a strength-inducing coating may be added between the desired locations for the plurality of weakened paths 160 .
- the adjustable covering 106 In creating the plurality of non-leaking tear paths 140 , it is desirable to form the adjustable covering 106 so that the adjustable covering 106 will not leak when in use. Thus, for example, straight-through perforations in the drape member 134 would not be satisfactory because the perforations would allow leaking by the adjustable covering 106 when reduced pressure was applied.
- Perforations may, however, be used in another embodiment.
- the drape member 134 may be formed with a first drape layer 174 and a second drape layer 176 .
- the first drape layer 174 has a first side 178 and a second, patient-facing side 180 .
- the second drape layer 176 has a first side 182 and a second, patient-facing side 184 .
- the second, patient-facing side 180 is adjacent to the first side 182 of the second drape layer 176 .
- the first drape layer 174 has a first perforated path 186 having a center line 188 .
- the first perforated path 186 may be formed with micro-perforations that weaken the first drape layer 174 and facilitate tearing.
- the second drape layer 176 has a second perforated path 190 with a center line 192 .
- the second perforated path 190 may also be formed with micro-perforations, which weaken the second drape layer 176 and facilitate tearing.
- the center line 188 of the first perforation path is displaced, or misregistered, from the center line 192 of the second perforation path 190 by a distance 194 .
- Distance 194 may be less than a few millimeters.
- An area of misregistration bounded by the first perforated path 186 and the second perforated path 190 defines a tear path of the plurality of non-leaking tear paths 140 .
- the misregistration allows the first and second perforation paths 186 , 190 to be sealed when not in use by the second and first drape layers 176 , 174 and to thereby avoid leaking.
- FIG. 7 shows the first and second drape layers 174 , 176 after the first support layer 135 and the releaseable backing layer 137 have been removed and the first perforation path 186 and the second perforation path 190 torn.
- the desired tear path of the plurality of non-leaking tear paths 140 is selected to allow the remaining portion of the adjustable covering 106 to be the desired size.
- Two portions of the tear starter of the first plurality of tear starters 150 aligning with the selected tear path desired are pulled away from each other to initiate a tear along the selected non-leaking tear path.
- the first tear starter 152 is shown being pulled in direction 196 and 198 to start the tear along the first non-leaking tear path 142 .
- the tear causes an associated weakened path of the plurality of weakened paths 160 to separate.
- the adjustable covering 106 is thereby sized.
- the drape member 134 may be formed with different segments having different drape grains and non-leaking tear paths may be formed parallel to the drape grains in each segment to provide a drape that may be torn in different directions. This would allow, for example, the adjustable covering 106 to be modified in at least two different directions—longitudinal and lateral directions.
